The eval scales and crop size of multi-scales evaluation can be found in [configs](./configs/). + +2. The fps is tested in different way from the paper. For more information, please see [here](./tensorrt). + +3. The authors of bisenetv2 used cocostuff-10k, while I used cocostuff-123k(do not know how to say, just same 118k train and 5k val images as object detection). Thus the results maybe different from paper. + +4. The authors did not report results on ade20k, thus there is no official training settings, here I simply provide a "make it work" result. Maybe the results on ade20k can be boosted with better settings. + +5. The model has a big variance, which means that the results of training for many times would vary within a relatively big margin. For example, if you train bisenetv2 on cityscapes for many times, you will observe that the result of **ss** evaluation of bisenetv2 varies between 73.1-75.1. + + +## deploy trained models + +1. tensorrt +You can go to [tensorrt](./tensorrt) for details. + +2. ncnn +You can go to [ncnn](./ncnn) for details. + +3. openvino +You can go to [openvino](./openvino) for details. + +4. tis +Triton Inference Server(TIS) provides a service solution of deployment.

Build with source code +Just use the standard cmake build method: +``` +mkdir -p tensorrt/build +cd tensorrt/build +cmake .. +make +``` +This would generate a `./segment` in the `tensorrt/build` directory. + + +#### 3. Convert onnx to tensorrt model +If you can successfully compile the source code, you can parse the onnx model to tensorrt model with one of the following commands. +For fp32, command is: +``` +$ ./segment compile /path/to/onnx.model /path/to/saved_model.trt +``` +If your gpu support acceleration with fp16 inferenece, you can add a `--fp16` option to in this step: +``` +$ ./segment compile /path/to/onnx.model /path/to/saved_model.trt --fp16 +``` +Building an int8 engine is also supported. Firstly, you should make sure your gpu support int8 inference, or you model will not be faster than fp16/fp32. Then you should prepare certain amount of images for int8 calibration. In this example, I use train set of cityscapes for calibration. The command is like this: +``` +$ rm calibrate_int8 # delete this if exists +$ ./segment compile /path/to/onnx.model /path/to/saved_model.trt --int8 /path/to/BiSeNet/datasets/cityscapes /path/to/BiSeNet/datasets/cityscapes/train.txt +``` +With the above commands, we will have an tensorrt engine named `saved_model.trt` generated. + +Note that I use the simplest method to parse the command line args, so please do **Not** change the order of the args in above command. + + +#### 4. Infer with one single image +Run inference like this: +``` +$ ./segment run /path/to/saved_model.trt /path/to/input/image.jpg /path/to/saved_img.jpg +``` + + +#### 5. Test speed +The speed depends on the specific gpu platform you are working on, you can test the fps on your gpu like this: +``` +$ ./segment test /path/to/saved_model.trt +``` + + +#### 6. Tips: +1. ~Since tensorrt 7.0.0 cannot parse well the `bilinear interpolation` op exported from pytorch, I replace them with pytorch `nn.PixelShuffle`, which would bring some performance overhead(more flops and parameters), and make inference a bit slower. Also due to the `nn.PixelShuffle` op, you **must** export the onnx model with input size to be *n* times of 32.~ +If you are using 7.2.3.4 or newer versions, you should not have problem with `interpolate` anymore. + +2. ~There would be some problem for tensorrt 7.0.0 to parse the `nn.AvgPool2d` op from pytorch with onnx opset11. So I use opset10 to export the model.~ +Likewise, you do not need to worry about this anymore with version newer than 7.2.3.4. + +3. The speed(fps) is tested on a single nvidia Tesla T4 gpu with `batchsize=1` and `cropsize=(1024,2048)`. Please note that T4 gpu is almost 2 times slower than 2080ti, you should evaluate the speed considering your own platform and cropsize. Also note that the performance would be affected if your gpu is concurrently working on other tasks. Please make sure no other program is running on your gpu when you test the speed. + +4. On my platform, after compiling with tensorrt, the model size of bisenetv1 is 29Mb(fp16) and 128Mb(fp32), and the size of bisenetv2 is 16Mb(fp16) and 42Mb(fp32). However, the fps of bisenetv1 is 68(fp16) and 23(fp32), while the fps of bisenetv2 is 59(fp16) and 21(fp32). It is obvious that bisenetv2 has fewer parameters than bisenetv1, but the speed is otherwise. I am not sure whether it is because tensorrt has worse optimization strategy in some ops used in bisenetv2(such as depthwise convolution) or because of the limitation of the gpu on different ops. Please tell me if you have better idea on this. + +5. int8 mode is not always greatly faster than fp16 mode. For example, I tested with bisenetv1-cityscapes and tensorrt 8.2.5.1. With v100 gpu and driver 515.65, the fp16/int8 fps is 185.89/186.85, while with t4 gpu and driver 450.80, it is 78.77/142.31. + + +### Using python + +You can also use python script to compile and run inference of your model. + + +#### 1. Compile model to onnx + +With this command: +``` +$ cd BiSeNet/tensorrt +$ python segment.py compile --onnx /path/to/model.onnx --savepth ./model.trt --quant fp16/fp32 +``` + +This will compile onnx model into tensorrt serialized engine, save save to `./model.trt`. + + +#### 2. Inference with Tensorrt + +Run Inference like this: +``` +$ python segment.py run --mdpth ./model.trt --impth ../example.png --outpth ./res.png +``` + +This will use the tensorrt model compiled above, and run inference with the example image. + diff --git a/cv/semantic_segmentation/bisenetv2/pytorch/tensorrt/batch_stream.hpp b/cv/semantic_segmentation/bisenetv2/pytorch/tensorrt/batch_stream.hpp new file mode 100755 index 0000000000000000000000000000000000000000..09d0262316ebd96c81db7779cbf72e9cfcaf645b --- /dev/null +++ b/cv/semantic_segmentation/bisenetv2/pytorch/tensorrt/batch_stream.hpp @@ -0,0 +1,148 @@ + +#ifndef BATCH_STREAM_HPP +#define BATCH_STREAM_HPP + + +#include +#include +#include +#include +#include +#include +#include +#include + +#include "NvInfer.h" +#include "read_img.hpp" + +using nvinfer1::Dims; +using nvinfer1::Dims3; +using nvinfer1::Dims4; + + +class IBatchStream +{ +public: + virtual void reset(int firstBatch) = 0; + virtual bool next() = 0; + virtual void skip(int skipCount) = 0; + virtual float* getBatch() = 0; + virtual int getBatchesRead() const = 0; + virtual int getBatchSize() const = 0; + virtual nvinfer1::Dims4 getDims() const = 0; +}; + + +class BatchStream : public IBatchStream +{ +public: + BatchStream(int batchSize, int maxBatches, Dims indim, + const std::string& dataRoot, + const std::string& dataFile) + : mBatchSize{batchSize} + , mMaxBatches{maxBatches} + { + mDims = Dims3(indim.d[1], indim.d[2], indim.d[3]); + + readDataFile(dataFile, dataRoot); + mSampleSize = std::accumulate( + mDims.d, mDims.d + mDims.nbDims, 1, std::multiplies()) * sizeof(float); + mData.resize(mSampleSize * mBatchSize); + } + + void reset(int firstBatch) override + { + cout << "mBatchCount: " << mBatchCount << endl; + mBatchCount = firstBatch; + } + + bool next() override + { + if (mBatchCount >= mMaxBatches) + { + return false; + } + ++mBatchCount; + return true; + } + + void skip(int skipCount) override + { + mBatchCount += skipCount; + } + + float* getBatch() override + { + int offset = mBatchCount * mBatchSize; + for (int i{0}; i < mBatchSize; ++i) { + int ind = offset + i; + read_data(mPaths[ind], &mData[i * mSampleSize], mDims.d[1], mDims.d[2]); + } + return mData.data(); + } + + int getBatchesRead() const override + { + return mBatchCount; + } + + int getBatchSize() const override + { + return mBatchSize; + } + + nvinfer1::Dims4 getDims() const override + { + return Dims4{mBatchSize, mDims.d[0], mDims.d[1], mDims.d[2]}; + } + +private: + void readDataFile(const std::string& dataFilePath, const std::string& dataRootPath) + { + std::ifstream file(dataFilePath, std::ios::in); + if (!file.is_open()) { + cout << "file open failed: " << dataFilePath << endl; + std::abort(); + } + std::stringstream ss; + file >> ss.rdbuf(); + file.close(); + + std::string impth; + int n_imgs = 0; + while (std::getline(ss, impth)) ++n_imgs; + ss.clear(); ss.seekg(0, std::ios::beg); + if (n_imgs <= 0) { + cout << "ann file is empty, cannot read image paths for int8 calibration: " + << dataFilePath << endl; + std::abort(); + } + + mPaths.resize(n_imgs); + for (int i{0}; i < n_imgs; ++i) { + std::getline(ss, impth, ','); + mPaths[i] = dataRootPath + "/" + impth; + std::getline(ss, impth); + } + if (mMaxBatches < 0) { + mMaxBatches = n_imgs / mBatchSize - 1; + } + if (mMaxBatches <= 0) { + cout << "must have at least 1 batch for calibration\n"; + std::abort(); + } + cout << "mMaxBatches = " << mMaxBatches << endl; + } + + + int mBatchSize{0}; + int mBatchCount{0}; + int mMaxBatches{0}; + Dims3 mDims{}; + std::vector mPaths; + std::vector mData; + int mSampleSize{0}; +}; + + +#endif diff --git a/cv/semantic_segmentation/bisenetv2/pytorch/tensorrt/entropy_calibrator.hpp b/cv/semantic_segmentation/bisenetv2/pytorch/tensorrt/entropy_calibrator.hpp new file mode 100755 index 0000000000000000000000000000000000000000..bc72ba47d21bd3a42fb592cc318e8b38e658cc94 --- /dev/null +++ b/cv/semantic_segmentation/bisenetv2/pytorch/tensorrt/entropy_calibrator.hpp @@ -0,0 +1,160 @@ +/* + * Copyright (c) 2019, NVIDIA CORPORATION.

of using trition-inference-serving + +### Platform + +* ubuntu 18.04 +* cmake-3.22.0 +* 8 Tesla T4 gpu + + +### Serving Model + +#### 1. prepare model repository + +We need to export our model to onnx and copy it to model repository: +``` +$ cd BiSeNet +$ python tools/export_onnx.py --config configs/bisenetv1_city.py --weight-path /path/to/your/model.pth --outpath ./model.onnx +$ cp -riv ./model.onnx tis/models/bisenetv1/1 + +$ python tools/export_onnx.py --config configs/bisenetv2_city.py --weight-path /path/to/your/model.pth --outpath ./model.onnx +$ cp -riv ./model.onnx tis/models/bisenetv2/1 +``` + +#### 2. prepare the preprocessing backend +We can use either python backend or cpp backend for preprocessing in the server side. +Firstly, we pull the docker image, and start a serving container: +``` +$ docker pull nvcr.io/nvidia/tritonserver:22.07-py3 +$ docker run -it --gpus all --rm -p8000:8000 -p8001:8001 -p8002:8002 -v /path/to/BiSeNet/tis/models:/models -v /path/to/BiSeNet/:/BiSeNet nvcr.io/nvidia/tritonserver:21.10-py3 bash +``` +From here on, we are in the container environment. Let's prepare the backends in the container: +``` +# ln -s /usr/local/bin/pip3.8 /usr/bin/pip3.8 +# /usr/bin/python3 -m pip install pillow +# apt update && apt install rapidjson-dev libopencv-dev +``` +Then we download cmake 3.22 and unzip in the container, we use this cmake 3.22 in the following operations. +We compile c++ backends: +``` +# cp -riv /BiSeNet/tis/self_backend /opt/tritonserver/backends +# chmod 777 /opt/tritonserver/backends/self_backend +# cd /opt/tritonserver/backends/self_backend +# mkdir -p build && cd build +# cmake .. && make -j4 +# mv -iuv libtriton_self_backend.so .. +``` +Utils now, we should have backends prepared. + + + +#### 3. start service +We start the server in the docker container, following the above steps: +``` +# tritonserver --model-repository=/models +``` +In general, the service would start now. You can check whether service has started by: +``` +$ curl -v localhost:8000/v2/health/ready +``` + +By default, we use gpu 0 and gpu 1, you can change configurations in the `config.pbtxt` file. + + +### Request with client + +We call the model service with both python and c++ method. + +From here on, we are at the client machine, rather than the server docker container. + + +#### 1. python method + +Firstly, we need to install dependency package: +``` +$ python -m pip install tritonclient[all]==2.15.0 +``` + +Then we can run the script for both http request and grpc request: +``` +$ cd BiSeNet/tis +$ python client_http.py # if you want to use http client +$ python client_grpc.py # if you want to use grpc client +``` + +This would generate a result file named `res.jpg` in `BiSeNet/tis` directory. + + +#### 2. c++ method + +We need to compile c++ client library from source: +``` +$ apt install rapidjson-dev +$ mkdir -p /data/ $$ cd /data/ +$ git clone https://github.com/triton-inference-server/client.git +$ cd client && git reset --hard da04158bc094925a56b +$ mkdir -p build && cd build +$ cmake -DCMAKE_INSTALL_PREFIX=/opt/triton_client -DTRITON_ENABLE_CC_HTTP=ON -DTRITON_ENABLE_CC_GRPC=ON -DTRITON_ENABLE_PERF_ANALYZER=OFF -DTRITON_ENABLE_PYTHON_HTTP=OFF -DTRITON_ENABLE_PYTHON_GRPC=OFF -DTRITON_ENABLE_JAVA_HTTP=OFF -DTRITON_ENABLE_GPU=ON -DTRITON_ENABLE_EXAMPLES=OFF -DTRITON_ENABLE_TESTS=ON .. +$ make cc-clients +``` +The above commands are exactly what I used to compile the library. I learned these commands from the official document. + +Also, We need to install `cmake` with version `3.22`. + +Optionally, I compiled opencv from source and install it to `/opt/opencv`. You can first skip this and see whether you meet problems. If you have problems about opencv in the following steps, you can compile opencv as what I do. + +After installing the dependencies, we can compile our c++ client: +``` +$ cd BiSeNet/tis/cpp_client +$ mkdir -p build && cd build +$ cmake .. && make +``` + +Finally, we run the client and see a result file named `res.jpg` generated: +``` + ./client +``` + + +### In the end + +This is a simple demo with only basic function. There are many other features that is useful, such as shared memory and dynamic batching. If you have interests on this, you can learn more in the official document. diff --git a/cv/semantic_segmentation/bisenetv2/pytorch/tis/client_backend.py
